Anti-TWEAK/Tnfsf12 Antibody Picoband®

Tumor necrosis factor ligand superfamily member 12 also known as TNF-related weak inducer of apoptosis (TWEAK) is a protein that in humans is encoded by the TNFSF12 gene. Predicted to enable receptor ligand activity. Acts upstream of or within extrinsic apoptotic signaling pathway. Located in extracellular region. Is expressed in Meckel's cartilage; hip; skeleton; and superior cervical ganglion. Orthologous to several human genes including TNFSF12-TNFSF13 (TNFSF12-TNFSF13 readthrough) .

Tumor necrosis factor ligand superfamily member 12; APO3 ligand; TNF-related weak inducer of apoptosis; TWEAK; Tumor necrosis factor ligand superfamily member 12, membrane form; Tumor necrosis factor ligand superfamily member 12, secreted form; TNFSF12; APO3L, DR3LG; UNQ181/PRO207

Highly expressed in adult heart, pancreas, skeletal muscle, brain, colon, small intestine, lung, ovary, prostate, spleen, lymph node, appendix and peripheral blood lymphocytes. Low expression in kidney, testis, liver, placenta, thymus and bone marrow. Also detected in fetal kidney, liver, lung and brain.

Binds to FN14 and possibly also to TNRFSF12/APO3. Weak inducer of apoptosis in some cell types. Mediates NF-kappa-B activation. Promotes angiogenesis and the proliferation of endothelial cells. Also involved in induction of inflammatory cytokines. Promotes IL8 secretion.
